DEVICE FOR HEATING SOLDERING-IRONS, LEAD-MELTING POTS, 8L0.

SPECIFIGATION forming part of Letters Patent No. 406,310, dated July 2,1889.

Application filed May 4, 1888. Serial No. 272,762. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN N. SANGER, a resident of the city of Brooklyn,Kings county, New York, have invented an Improved Device for HeatingSoldering-Irons, Lead-Meltin g Pots, &c., of which the following is aspecification.

The object of my invention is to provide an improved device for heatingsoldering-irons, lead-melting pots, &c.

The invention consistsin the details of improvement and the combinationsof parts, that will be more fully hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which- Figure 1 is a side elevation of aheatingdevice embodying my improvements. Fig. 2 is a vertical cross-section 0nthe line 0 c, Fig. 1, showing a soldering-iron in position. Fig. 3 is avertical central section of the tool-support, shown inverted and holdinga lead-pot Fig. 4. is a top view of the gas-distributing plate that fitson the gas and air supply pipe, and Fig. 5 is a vertical cross-sectionof the same and its gas-pipe.

In the accompanying drawings, the letter A represents a plate thatpreferably has a number of openings for the passage of air. The plate Ais adapted to be placed on a workbench d, over an opening therein, andit is provided with lugs b, that pass into the bench to to prevent itsturning; or the plate A may be otherwise held. The plate A is providedat its center with air aperture (1, having internal screw-thread. A gasand air pipe B, having external screw-thread, passes through saidaperture (1, its thread meshing with the thread in said aperture. At itslower end the pipe B is provided with an air bulb or chamber f, that hasa number of openings for the admission of air, as shown. A gas-supplynipple g enters this chamber f to deliver gas. This nipple g or itsgas-supply pipe may have a suitable cock h to regulate the supply ofgas. Air from the chamber f and the gas from the pipe g enter the pipe Band mingle therein, so as to burn at the upper end of said pipe in ablue flame. WVhen used to heat a soldering-iron D, I prefer todistribute the flame, and for this purpose I place a plate 2' over theend of the pipe B, and at a little distance therefrom. This plated issupported by arms j, that project from an internallythreaded ring or nutZ, that fits on the end of the pipe B, as clearly shown in 5. The platet' forms a convenient burner, and when the mixture of gas and air fromthe pipe B strikes the plate 2' it is deflected and passes outward frombetween the top of the pipe and the plate, and burns in a ring aroundsaid plate.

E is a stove and support for the solderingiron or lead-pot, and is inthe form of a jacket or heat-retainer. The stove E is open at the bottomand is adapted to rest on the plate A, the pipe B passing within thesame, as shown in Fig. 2.

The stove E is substantially dome-shaped at one end, and is providedwith an internal perforated partition m, that is above the pipe B, as inFig. 2. The stove E has an opening a at its upper end to permit theescape of the products of combustion from the burner. The opening a alsoserves to permit the passage of the pipe B, as hereinafter shown. Airenters through the plate A, to support oombustion of the. gas-mixture.

Above the perforated partition m the stove E is provided with an openinga in the side, to permit the passage of a soldering-iron D or other toolto be heated.

The soldering-iron enters through the opening a and rests near one endon the partition on, while its handle rests on a rail 'n, that issupported on the outside of the stove E. This rail n is the outer edgeof a cup or receptacle 0, that is carried on the stove E, as in Figs. 1and 2. Tin or solder may be kept in this cup 0.

The stove E is or may be provided with a suitable handle 9.

When it is desired to heat the solderingiron D or other tool, the stoveE is placed on the plate A and over the pipe B, in the posi tion shownin Figs. 1 and 2. The gas is then lighted, and if the flame is too nearor far from the iron D the pipe B may be lowered or raised by turningsame, its thread causing it to descend through the plate A the desireddistance; or, if preferred, the plate A may be turned to cause it tomove the pipe up or down. When it is desired to melt lead 01; the like,the stove E is reversed, as shown in Fig. 3, the pipe B passing throughthe opening a in the dome, as shown. Air enters to support combustionthrough the opening a or around the pipe B. The lead-pot F is thenplaced in the top of the stove E, the projections b on the pot F restingon the stove E; or the pot may be otherwise supported, either on acontraction of the stove E or on the par-' tition m. For heating thispot F, I may remove the plate 11 and permit the direct flame from theopen end of the pipe B to strike the pot F and spread around the same.

This device will be easily managed, is simple and effective in itsoperation, and not easy to get out of order. The heat from the flame isretained within the stove to a great extent, thereby adding to theeffectiveness of the device.

Havin now described my invention, What I claim isa 1. The stove E,having openings at both ends that are larger than the gas-supply pipe,internal perforated plate m, side opening a above said plate, andexternal cup 0, having raised ledge 02, that acts as a tool-rest,substantially as herein shown and described.

2. The combination of the plate A, having the internally-screw-threadedcollar (Z,with the externally-screW-thread ed pipe B fitting saidcollar, the reversible stove E, open at both ends, one end being adaptedto rest on the late A, the opening in the opposite end being larger thanthe pipe B, said stove having the internal perforated plate m and theopening a whereby the stove may be used either as a solder orsoldering-iron heater, substan- WVitnesses:
